A rotating and fixing structure for the horizontal arm of a mobile X-ray machine

Abstract

This application discloses a rotating and fixing structure for a mobile X-ray machine's horizontal arm, relating to the field of mobile X-ray machines. It includes a balancing component housed inside a support frame for dynamically matching the torque requirements of X-ray tubes of different weights. The support frame also houses a locking component to prevent accidental displacement of the horizontal arm when it is in its lowest position. This application adjusts the spring force of spring one by rotating a hexagonal prism, thereby dynamically matching the torque requirements of X-ray tubes of different weights. This allows the horizontal arm to achieve precise self-balancing at any rotation angle, significantly reducing operational resistance, especially during vertical lifting. When the horizontal arm body drives the locking pin to the lowest working position within the rotation range, the slider, through the movement of spring three, forms a closed circle with the fixing block, locking the locking pin. The physical locking of the locking pin, combined with the spring force pre-tightening device, prevents accidental displacement caused by sudden external forces.

Description

Technical Field

[0001] This application relates to the field of mobile X-ray machines, and more particularly to a structure for rotating and fixing the crossarm of a mobile X-ray machine. Background Technology

[0002] A mobile X-ray machine is a portable medical imaging device that emits X-rays to penetrate human tissue and generate images, helping doctors diagnose diseases or monitor during surgery.

[0003] As the core moving component of the mobile X-ray machine, the stability and safety of the transverse arm are directly related to the accuracy of medical examinations and the safety of operators and patients. Currently, the transverse arm structure often fails to maintain balance due to changes in the weight of the X-ray tube. During the raising and lowering of the transverse arm, the fixed spring system cannot compensate for inertial impacts in real time, which can easily cause the X-ray tube to shake, resulting in blurred images. This is especially true during bedside chest X-rays, which require repeated positioning and increase the risk of radiation exposure for patients. Utility Model Content

[0004] To improve the problem of balance failure caused by changes in the weight of the X-ray tube, this application provides a rotating and fixing structure for the horizontal arm of a mobile X-ray machine.

[0005] The technical solution for the rotating and fixing structure of a mobile X-ray machine's transverse arm provided in this application is as follows:

[0006] A rotating and fixing structure for a mobile X-ray machine's transverse arm includes a balancing component disposed inside a support frame for dynamically matching X-ray tubes of different weights, and a locking component disposed inside the support frame for preventing accidental displacement of the transverse arm when it is in its lowest position.

[0007] By adopting the above technical solution, the balancing component is used to dynamically match the torque requirements of different weight tubes, so that the horizontal arm can achieve precise self-balancing at any rotation angle. The locking component is used to provide double protection when the horizontal arm is at its lowest position, ensuring that the horizontal arm will not suddenly spring up and accidentally injure other people.

[0008] Preferably, the balancing assembly includes a fixed plate fixedly connected to the inner wall of the support frame, a square plate slidably connected inside the fixed plate, a chain rotatably connected to one side of the square plate, and a lead screw fixedly connected to the side of the square plate away from the chain.

[0009] By adopting the above technical solution, the sliding connection between the fixed plate and the square plate achieves high rigidity guidance, reduces the interference of lateral force on the lead screw, and also prevents the adjustment of the hexagonal square plate from causing the spring to rotate.

[0010] Preferably, a circular ring plate is slidably connected to the inner wall of the support frame on one side of the surface of the lead screw, and a hexagonal prism is rotatably connected to the surface of the lead screw on one side of the surface of the circular ring plate. A spring sleeved on the outside of the lead screw and the square plate is fixedly connected between the surface of the circular ring plate and the surface of the fixed plate.

[0011] By adopting the above technical solution, the preload of spring one is evenly distributed through the annular plate, avoiding the screw from bearing eccentric stress and extending the screw life.

[0012] Preferably, the support frame has a through groove on its exterior for easy adjustment of the hexagonal prism.

[0013] By adopting the above technical solution, the through slot allows the hexagonal prism to be adjusted directly with tools, and the spring preload calibration can be completed without disassembling the outer shell, thus reducing maintenance costs.

[0014] Preferably, the locking assembly includes a fixing block that is fixedly connected through the inside of the support frame, and a groove is provided on the surface of the support frame near the fixing block. A slider that forms a circular hole with the inner side of the fixing block is slidably connected inside the groove.

[0015] By adopting the above technical solution, the circular hole formed by the fixed block and the slider provides multi-directional limiting, and in conjunction with the sliding path of the slide groove, ensures that there is no play when the locking pin is inserted.

[0016] Preferably, a cylinder is slidably connected to the inner side of the fixing block and the slider, and a ring strip slidably connected to the inner side of the slider is fixedly connected to the outer surface of the cylinder near the slider. A spring is fixedly connected between one side of the cylinder surface and the inner side of the fixing block.

[0017] By adopting the above technical solution, the spring-driven cylinder automatically rebounds, preventing objects from blocking the cylinder without locking it.

[0018] Preferably, the inner wall of the support frame is fixedly connected to a cylinder that extends into the slide groove, and a sliding column that is fixedly connected to the inner wall of the slider is slidably connected inside the cylinder. A spring is fixedly connected between one end of the sliding column inside the cylinder and the inner wall of the cylinder.

[0019] By adopting the above technical solution, the sliding cooperation between the sliding column and the cylinder provides guiding stability and ensures the accurate movement trajectory of the slider.

[0020] A rotating structure for the horizontal arm of a mobile X-ray machine includes a support frame, and the aforementioned fixing structure for the horizontal arm of a mobile X-ray machine is disposed inside the support frame.

[0021] By adopting the above technical solution, the fixed structure is embedded into the rotating system, thereby decoupling dynamic balance from rotational degrees of freedom. The balancing component works continuously when the horizontal arm rotates, avoiding torque imbalance caused by angle changes.

[0022] Preferably, the support frame has a rotating shaft rotatably connected through it, and a cross arm body for connecting the X-ray machine tube is rotatably connected to the outer surface of the rotating shaft. The cross arm body can rotate around the rotating shaft. A locking pin is fixedly connected through one side of the surface of the cross arm body. Square block one and square block two are fixedly connected to the outer surface of the rotating shaft. A square groove one that fits the surface of square block one and is adapted to the size of square block one is opened through the surface of the cross arm body.

[0023] By adopting the above technical solution, square block one and square block two drive the rotating shaft and the sector block to rotate through the shape setting.

[0024] Preferably, it also includes a sector block fixedly connected to the end of the chain away from the square plate. A square groove is provided on one side of the surface of the sector block, which is fitted onto the surface of the square block and is adapted to the size of the square block. A limiting block is rotatably connected to the surface of the rotating shaft and fixedly connected to the inner wall of the support frame. A limiting groove is provided on one side of the surface of the sector block, and the inside of the limiting groove is slidably connected to the limiting block.

[0025] By adopting the above technical solution, the limiting block and the limiting groove restrict the rotation angle of the sector block, thus avoiding mechanical interference caused by the horizontal arm rotating beyond its range.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The spring force of spring one is adjusted by rotating the hexagonal prism, thereby dynamically matching the torque requirements of ball tubes of different weights, so that the horizontal arm can achieve precise self-balancing at any rotation angle, and significantly reducing operating resistance, especially during vertical lifting.

[0028] 2. When the horizontal arm body drives the locking pin to the lowest working position of the rotation range, the use of the ring bar causes the slider to be squeezed by the locking pin, which in turn drives the cylinder to move simultaneously. This prevents the cylinder from being higher than the locking pin and thus failing to lock successfully. When the locking pin enters the range of the cylinder, the slider moves with the fixed block through the movement of the spring three to form a closed circle, locking the locking pin. The physical locking of the locking pin, combined with the spring force pre-tightening device, can prevent accidental displacement caused by sudden external force and eliminate the risk of sudden release of spring energy. When the horizontal arm body moves in other ranges, the cylinder blocks the locking hole formed by the fixed block and the slider through the spring two, preventing other objects from blocking the locking hole and causing the locking pin to fail to lock.

[0029] 3. By using the limiting groove and limiting block, the horizontal arm body can rotate within the range of -54° to +40°, preventing excessive rotation of the horizontal arm body. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0040] Example 1

[0041] This application discloses a crossarm fixing structure for a mobile X-ray machine.

[0042] Reference Figure 2 , Figure 6 A mobile X-ray machine crossarm fixing structure includes a balancing component 2 installed inside a support frame 1. The balancing component 2 is used to dynamically match X-ray tubes of different weights to achieve crossarm angle adjustment and balance control. A locking component 3 is installed inside the support frame 1 to prevent accidental displacement of the crossarm when it is at its lowest position.

[0043] Reference Figure 2 , Figure 4The balancing assembly 2 includes a fixed plate 21 fixedly connected to the inner wall of the support frame 1. The inner wall of the fixed plate 21 is slidably connected to the outer wall of the square plate 22, and there is no gap between the inner wall of the fixed plate 21 and the outer wall of the square plate 22, so that the square plate 22 will not shift or shake during sliding. The top of the square plate 22 is rotatably connected to the bottom end of the chain 23. The movement of the chain 23 drives the square plate 22 to slide inside the fixed plate 21. The surface of the square plate 22 is fixed to the top of the lead screw 24. The lead screw 24 is connected to the end of the square plate 22 away from the chain 23, and the bottom surface of the lead screw 24 is slidably connected to the inner wall of the ring plate 26. The ring plate 26 is seamlessly connected to the inner wall of the support frame 1. The bottom of the ring plate 26 is rotatably connected to the hexagonal prism 27. The inner side of the hexagonal prism 27 is threadedly connected to the outer surface of the lead screw 24. The preload of the spring 25 is adjusted by rotating the hexagonal prism 27 to drive the ring plate 26 to slide on the surface of the lead screw 24. The top surface of the ring plate 26 and the bottom surface of the fixing plate 21 are respectively fixed to the two ends of the spring 25. The spring 25 is sleeved on the outer surface of the square plate 22 and the lead screw 24. The support frame 1 has a through groove 28 on its outside. The through groove 28 is used to facilitate the adjustment of the preload of the spring 25 by the staff.

[0044] When the operator rotates and adjusts the angle of the horizontal arm body 4, it will drive the chain 23 to move. The movement of the chain 23 will cause the square plate 22 to slide inside the fixed plate 21. The movement of the square plate 22 will drive the lead screw 24 to move. The movement of the lead screw 24 will drive the circular plate 26 to move through the hexagonal prism 27 to compress the spring 25. The compression of the spring 25 will be controlled, and the elastic force generated by the spring 25 will be adjusted in real time to offset the torque difference caused by the weight of the ball tube at different rotation angles of the horizontal arm body 4. When changing to a ball tube of different weights, the initial spring force of the spring 25 will be adjusted by rotating the hexagonal prism 27 to compress or relax the circular plate 26, thereby dynamically matching the torque requirements of ball tubes of different weights.

[0045] Reference Figure 5 , Figure 6 The locking assembly 3 includes a fixing block 31 that is fixedly connected to the inside of the support frame 1. The surface of the support frame 1 is provided with a sliding groove 33. The sliding groove 33 is symmetrical to the fixing block 31. The fixing block 31 is semi-circular. The inner wall of the sliding groove 33 slides and has no gap with the outer wall of the slider 32. The middle and top of the outer wall of the slider 32 are inclined so that the locking pin 5 will not be blocked when it rotates to the surface of the slider 32. The inclined shape facilitates the squeezing of the slider 32. The outer contours of the fixing block 31 and the slider 32 are symmetrical with the middle and upper inner sides. The inner sides of the fixing block 31 and the slider 32 are combined to form a circular hole.

[0046] The locking component 3 is set on the rotation trajectory of the horizontal arm body 4 and the locking pin 5. When the horizontal arm body 4 drives the locking pin 5 to rotate to the lowest position, the locking pin 5 will squeeze the slider 32 into the round hole formed by the combination of the fixed block 31 and the slider 32 and lock it to prevent displacement.

[0047] Reference Figure 5 , Figure 6 The inner wall of the circular hole formed by the combination of the fixing block 31 and the slider 32 slides against the surface of the cylinder 34. The size of the cylinder 34 is adapted to the inner wall of the fixing block 31 and the slider 32. When the cross arm body 4 moves in other ranges, the cylinder 34 blocks the locking hole formed by the fixing block 31 and the slider 32 to prevent other objects from blocking the locking hole and causing the locking pin 5 to be unable to lock. The outer wall of the cylinder 34 is fixedly connected to the ring strip 35. The ring strip 35 is set on the side close to the slider 32. The ring strip 35 is inserted into the interior of the slider 32 and is slidably connected to the inner wall of the slider 32. The bottom of the cylinder 34 is fixed to the top of the spring 36. The bottom end of spring 36 is fixed to the inner bottom of the fixed block 31. A ring bar 35 that is slidably connected to the outer surface of the cylinder 34 near the slider 32 is fixedly connected to the outer surface of the cylinder 32. The bottom of the support frame 1 is fixed to the outer surface of the cylinder 37. The cylinder 37 passes through the interior of the support frame 1 to the interior of the slide groove 33. The inner wall of the cylinder 37 is slidably connected to the outer wall of the slide column 39. The bottom of the slide column 39 is fixed to the top of spring 38. The bottom end of spring 38 is fixed to the bottom of the inner wall of the cylinder 37. The outer surface of the slider 32 is fixedly connected to the inner side of the pressing plate 310. The pressing plate 310 slides inside the support frame 1.

[0048] When the horizontal arm body 4 drives the locking pin 5 to the lowest working position of the rotation range, the inclined surface of the slider 32 is squeezed by the locking pin 5 and moves downward. The movement of the slider 32 drives the sliding column 39 to slide inside the cylinder 37 and squeeze the spring 38. When the slider 32 moves, it drives the cylinder 34 to move downward through the ring bar 35 and squeeze the spring 36. The slider 32 and the cylinder 34 move downward at the same time to prevent the cylinder 34 from being higher than the locking pin 5 and failing to lock successfully. When the top of the slider 32 and the cylinder 34 move to be parallel to the side of the support frame 1, the locking pin 5 moves to the inside of the fixed block 31 and cannot move. The locking pin 5 enters the range of the cylinder 34. The slider 32 moves upward to reset by the elastic force of the spring 38. The slider 32 and the fixed block 31 form a closed circle to lock the locking pin 5. When the horizontal arm body 4 needs to move, it is only necessary to press the pressing plate 310. The pressing plate 310 drives the slider 32 to move and open the closed circle formed by the slider 32 and the fixed block 31. The horizontal arm body 4 can drive the locking pin 5 to rotate.

[0049] The locking pin 5 has an arc-shaped edge near the support frame 1, and the arc angle of the locking pin 5 is greater than the tilt angle of the slider 32. In this way, when the locking pin 5 is rotated to the lowest position, it can slide accurately and efficiently into the slider 32. The part of the locking pin 5 located between the cross arm body 4 and the support frame 1 is the locking part. The spring 38 can be compressed a distance greater than the distance of the locking part of the locking pin 5.

[0050] It should be noted that the calculation formula for spring 1 (25), spring 2 (36), and spring 3 (38) is: F = kx, where F is the external force on the spring (N), k is the spring constant (N / m), and x is the deformation of the spring (m). This formula is used to calculate the elastic force of the alloy spring so that it can be used in this device.

[0051] The implementation principle of the mobile X-ray machine's horizontal arm rotation and fixing structure in this application embodiment is as follows: In the initial state, springs 25, 36, and 38 are not compressed. When it is necessary to adjust the angle of the horizontal arm body 4 supporting the X-ray tube, the operator rotates the horizontal arm body 4, which drives the square plate 22 and the lead screw 24 to move through the chain 23. The movement of the lead screw 24 drives the circular plate 26 to move through the hexagonal prism 27, compressing spring 25 and controlling the compression of spring 25. The elastic force generated by spring 25 is adjusted in real time to offset the torque difference caused by the weight of the X-ray tube at different rotation angles of the horizontal arm body 4. When changing X-ray tubes of different weights, the spring force of spring 25 is adjusted by the rotation of the hexagonal prism 27, thereby dynamically matching the torque requirements of X-ray tubes of different weights. This allows the horizontal arm to achieve precise self-balancing at any rotation angle, and significantly reduces operating resistance, especially during vertical lifting.

[0052] When the horizontal arm body 4 drives the locking pin 5 to the lowest working position of the rotation range, the locking pin 5 presses the slider 32 and drives the cylinder 34 to move simultaneously through the ring bar 35, preventing the cylinder 34 from being higher than the locking pin 5 and failing to lock successfully. When the locking pin 5 enters the range of the cylinder 34, the slider 32 rebounds through the spring 38 and forms a closed circle with the fixing block 31 to lock the locking pin 5. The physical locking of the locking pin 5, combined with the spring force pre-tightening device, can prevent accidental displacement caused by sudden external force and eliminate the risk of sudden release of spring energy. When the horizontal arm body 4 needs to move, the operator only needs to press the pressing plate 310 fixed to the slider 32, and the horizontal arm body 4 can drive the locking pin 5 to rotate.

[0053] Example 2

[0054] The difference from Embodiment 1 is that a mobile X-ray machine horizontal arm rotation structure includes a support frame 1. The support frame 1 has the aforementioned mobile X-ray machine horizontal arm fixing structure inside. The top end of the support frame 1 is rotatably connected to a rotating shaft 6, which passes through both sides of the support frame 1. The surface of the rotating shaft 6 located outside the support frame 1 is rotatably connected to the horizontal arm body 4. The horizontal arm body 4 is used to connect the X-ray machine tube and can rotate around the rotating shaft 6. The side of the horizontal arm body 4 near the slider 32 is fixedly connected to a locking pin 5, which passes through the horizontal arm body. On one side of 4, the locking pin 5 is adapted to the size of the cylinder 34 at one end near the support frame 1. One end surface of the rotating shaft 6 is fixedly connected to the square block 7, and the middle surface of the rotating shaft 6 is fixedly connected to the square block 8. The square blocks 7 and 8 are square and are used to drive the square blocks 7 and 8 to rotate when the horizontal arm body 4 rotates. A square groove 9 is provided on the side of the horizontal arm body 4 near the square block 7. The size of the square groove 9 is adapted to the outer wall size of the square block 7. The horizontal arm body 4 is fitted onto the outer surface of the square block 7 through the square groove 9.

[0055] When the horizontal arm body 4 rotates to adjust the angle, it drives the square block 7 to rotate through the square groove 9, which in turn drives the rotating shaft 6 to rotate through the square block 7.

[0056] A rotating structure for a mobile X-ray machine's horizontal arm also includes a sector block 10 fixedly connected to the end of a chain 23 away from a square plate 22. The chain 23 is located on the sector surface of the sector block 10. A square groove 11 is formed on the outer surface of the sector block 10, penetrating the interior of the sector block 10. The sector block 10 is fitted onto the outer surface of a square block 8 through the square groove 11. The size of the square groove 11 is adapted to the outer wall size of the square block 8. A rotating shaft 6 is rotatably connected to the inner side of a limiting block 12 near one end of a square block 7 and positioned on one side of the sector block 10. The side of the limiting block 12 away from the sector block 10 is fixed to the inner wall of the top of the support frame 1. The end of the limiting block 12 near the sector block 10 protrudes. A limiting groove 13 is opened on the side of the sector block 10 near the limiting block 12. The limiting groove 13 is set to 184 degrees. The angle on both sides of the protruding end of the limiting block 12 is 90 degrees. The two sides of the protruding end of the limiting block 12 are collinear with the radius of the limiting block 12. The inside of the limiting groove 13 is slidably connected to the limiting block 12. In this way, the rotation angle of the sector block 10 is 94 degrees, and the horizontal arm body 4 can rotate within the range of -54° to +40°.

[0057] The rotating shaft 6 is driven to rotate by the square block 7, which in turn drives the sector block 10 to rotate via the square block 8. Since the protruding end of the limiting block 12 is located inside the limiting groove 13, the rotation range of the horizontal arm body 4 is restricted when the sector block 10 rotates.

[0058] The implementation principle of the horizontal arm rotation and fixing structure of the mobile X-ray machine in this application embodiment is as follows: When the horizontal arm body 4 rotates to adjust the angle, the rotating shaft 6 is driven to rotate through the matching of square groove 1 9 and square block 1 7. The rotation of the rotating shaft 6 drives the fan-shaped block 10 to rotate through the matching of square block 2 8 and square groove 2 11. The rotation of the fan-shaped block 10 is restricted by the limiting block 12 and the limiting groove 13, so that the horizontal arm body 4 can rotate within the range of -54° to +40°, preventing the horizontal arm body 4 from rotating excessively.

[0059] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
